A telecommunications digital signal cross-connect panel for interfacing multiplexer equipment having as many as 84 circuits and digital loop carrier equipment having at least 84 circuits. The panel includes 84 multiplexer ports, 84 carrier ports, 84 multiplexer cross-connect ports, and 84 carrier cross-connect ports. The panel also includes edge connector sockets which are each electrically connected to a corresponding one of the multiplexer cross-connect ports and a corresponding one of the multiplexer ports. The panel includes two edge connector cards which are each selectively insertable by the user into individual ones of the 84 edge connector sockets. Each of the edge connector cards is connected by a cable to a set of test access sockets. When an edge connector card is inserted into a selected edge connector socket, two sets of contacts of the selected edge connector socket move out of electrical connection with each other and move into electrical contact with the corresponding contacts of the inserted edge connector card. The edge connector sockets are 'make before break' sockets which make contact with the card contacts before the two sets of socket contacts break contact.
